West Bromwich Albion have rejected a bid from QPR believed to be worth around £5m for their Swedish defender Jonas Olsson.

Olsson signed a new four-year contract with the club in October, but is reported to be keen on a move to London for family reasons. He is understood, though, to have reservations about a move to Loftus Road given their precarious position in the Premier League.

The West Brom manager, Steve

Clarke said: "I can confirm a bid has been turned down and I don't encourage any more bids because Jonas is not for sale.

"I have spoken to Jonas and he says he is loving the football here and is looking forward to the rest of the season.

"He will remain a West Brom player and we don't have to sell anyone. He is not for sale so there is no figure which is reasonable."

But when asked if there was a buy-out clause, Clarke said: "There is a clause in Jonas' contract which comes into play during the summer. There are six clubs that can invoke that."

QPR's manager Harry Redknapp has made no secret of his desire to strengthen his defence during the transfer window. That need has been increased by the fact that Ryan Nelsen has agreed to become the head coach of Major League Soccer side Toronto FC.

The 35-year-old has been one of the side's best players this season, but admits he is "playing on glass knees and glass ankles" and is hoping to negotiate an early exit from Loftus Road.

Robert Green, meanwhile, has distanced himself from links to Nottingham Forest. The QPR goalkeeper has lost his place to Júlio César, but told TalkSport: "This is the first I've heard. I don't know anything about it."
